Late autumn eggplant cultivation is performed at the end of June to early July. It is planted from the end of August to the middle of September. Harvesting begins at the end of October and continues through the seasons from the end of December to the beginning of January.
I. Selection of good disease-resistant varieties
The late fall of the greenhouse and late eggplant pollution-free cultivation of the nursery period coincides with high temperature and rain, and the result is in the low temperature and cold season, should choose the heat and disease resistance, resistant to low temperature and weak light growth potential varieties, such as the seven-leaf eggplant, Nine leaves eggplant, purple long eggplant, large dragon long eggplant and so on.
Second, nursery
The breeding of this quail eggplant is in the high temperature season, and it is generally used in Putian live seedlings. To avoid burning seedlings with high temperature and direct sunlight, it is best to use sunshade nets to cover the seedlings.
1, soaking seed germination before soaking seed treatment with pesticides can prevent pests and diseases. One of the methods is soaking with 300-fold formalin solution for 10 minutes, or soaking with 500-times liquid 50% DT fungicide for 20 minutes, then remove the washing solution to soak.
2, sowing hot weather in June, the best choice for cloudy sowing. Put enough water in the bowl. When the water seeps, sprinkle a layer of nutrient soil. Spread the seeds evenly on the bed, then cover the soil 1-1.5 cm.
3, shading and rain sowing seedbed shade net shade or in the seedlings take some shelves covered with straw, not only shade but also cool rain. When the shoots are flushed, moisturizing should be taken to prevent the seedbeds from drying and damaging the roots. In order to improve the quality of nursery, nursery boxes can also be used to nurse seedlings, nutrition and seedling methods.
Third, colonization
Before the planting, the greenhouse must be disinfected to prevent diseases. The method is to ignite every cubic meter of space with 5 grams of sulfur powder, 0.1 grams of dichlorvos EC, and 20 grams of sawdust. Soil preparation and fertilization: The absorption of fertilizer by eggplant during the production process is relatively large. In order to ensure that there is no shortage of fertilizer in the production, the per acre is applied to mature fertilizer or fermented biogas slurry 5000-7000 kilograms, superphosphate and potassium sulfate each 15 kilograms. After fertilizing the soil, the ground is flattened, and the ridges are laid at a row spacing of 60 cm and the ridge height is 10-15 cm. When planting, select cloudy or late evening assault. The distance between plants is 35 cm, and the planting density per acre is 3500-4000 strains. Immerse water immediately after colonization.
Fourth, field management
1, cultivating weeds and planting 3-4 days after pouring a phlegm water, in order to facilitate the rooting of eggplant. After pouring the larvae, the surface of the alfalfa has not yet dried out, and the cultivating and weeding are carried out immediately to facilitate the preservation of water, ventilation, and promotion of the development of the root system. Then, according to the condition of eggplant hair, continuous cultivating 2-3 times, especially pay attention to the cultivator after raining or running in the field to prevent soil compaction.
2, watering After 2-3 times of cultivator weeding and other measures, the eggplant gradually began to grow. After 20-25 days of general colonization, it is ready to water. The head water must be drenched with small water, avoid flooding. _
3, after fertilization easing seedlings combined with watering per acre full of organic fertilizer or decomposition of biogas slurry 1000-1500 kilograms, after flowering in conjunction with water per acre and then chase a decomposed organic fertilizer and diammonium phosphate or urea 10-15 kg . Diammonium phosphate and urea should be applied deeply. The number of topdressing should be increased after the door and socket are expanded. However, the amount of chemical fertilizer should be controlled, and the foliar spray of nitrogen fertilizer should be prohibited.
4. The cold temperature in the cold areas of the shed management changes greatly during the night after September. Frost has already appeared at the end of September, so it is necessary to buckle the membrane at any time according to weather changes. It is best to press the film 7-10 days before the arrival of the early frost, or to take the film in time when the night temperature is less than 15°C. Reduce the ventilation gradually as the weather gets colder.
When flowering the eggplant or the four-door douche, increase the fruit setting rate with 2,4-D or anti-declining pods, and then press the door to the eggplant, the tomato to the three pods, the four-door douche, or the door to the eggplant. 2-4 pruning of eggplant and four-door hoppers, timely removing the old leaves at the bottom and excess side branches. When the room temperature is lower than 15°C, it is necessary to make up the temperature in time. When the temperature exceeds 30°C, it must be ventilated and cooled.
